The Secret Society of Super-Villains
Dr. Crystal Frost was an extremely withdrawn young woman who sought to be accepted as an equal by her fellow scientist, but felt herself instead to be the victim of prejudice against women. While studying at Hudson University she fell in love with one of her teachers, Dr. Martin Stein. Years later, Stein visited a scientific project she was working on in the Arctic. She was shocked to learn that Stein was not and never had been in love with her.
Dr. Frost accidentally locked herself in a thermofrost chamber, and as a result was transformed into a super-human being. Calling herself Killer Frost, she sought vengeance on her allegedly prejudiced male colleagues and on Stein by absorbing all the heat from their bodies. However, Stein joined with student Ronnie Raymond to become Firestorm, who defeated Killer Frost.
